Original application filed "May 16, 1910,

To all whom it may concern) Be it known that 1, CHARLES. C. Hansen, f a citizen of the United States, and resident of Easton, in the county of Northampton and State of Pennsylvania, have invented a new and useful Improvement in Oilers, oi :Whichthe following is a specification.

This invention comprises a novel oiler intended to be used in connection with a pressure fluid operated engine, such, for instance, as a rock drill, the said oiler comprising an oil impregnated cartridge located in position to have the oil extracted therefrom in small quantities by variations in the fluid pressure due to the operation of the engine. 1 'Practical embodiments of this invention are represented in the accompanying drawing, in whichv Figure 1 represents the oiler...as located in the fluid pressure'supply passage between the pressure fluid controlling valve and the valve chest of the engine, certain of the parts being shown in side elevation and certain of the parts in section, Fig. 2 is a similar view showing the. oiler located directly in the valve chest, Fig. 3 is a detail sectional view showing the oiler located in a passage incommunication with the interior of the valve chest of the engine, Fig. 4 is' a detail side view of one form of cartridge. receiving shell, Fig. 5 represents the several parts or" the cartridge disassembled, Fig. 6 is a perspective view of the cartridge carryingbox used for transportation purposes, a portion of the same being broken awa to I show .a-cartridge located therein, and *igr 7 is an enlarged detail cross section through. the cartridge body to more clearly illustrate its structure.

The cartridge proper comprises a body '1 and its carrying pin 2, screw plug 3 and means for securing the body 1 on the pin 2, in the present instance comprising washers 4. and cotter pin 5. The body portion 1 is arranged to be impregnated with the lubricating oil, which body portion is herein shown as comprising a strip of fabric such as flannel or cotton and a strip of brass wire netting rolled together around the pin 2. By this arrangement a porous mass is provided which will contain a considerable amount of lubricating oil. This cartridge is introduced into a chamber or passage in communication with the pressure fluid sup- Speelfication of Letters Patent.

1 ply operating the engine so as to be subjected to thefluctuations in pressure or, in other words, the pulsations due to the operation of the engine. This introduction of the o l impregnated cartridge into coinmunlcation with the fluid pressure supply for the engine may be accomplished in various ways, several of which are herein illustrated andwill be now described Referring to Fig. 1, a hollow coupling 6- is-connected to the fluid pressure supply pipe 7 and valve chest8 of the engine. The

fluid pressure supply pipe '2 is provided With the usual fluid pressure controlling valve 9. A hollow shell 10 is screwed into the coupling 6. This hollow shell is pro-,

vided with one or more openings 11 at its nner endwithm the coupling 6 for bringmg the interior of the shell into open com- -munication with the interior of the coupling 6. The cartridge is inserted into the shell 10 and'heldin its position therein by the screw threaded engagement of the plug 3 with the outer end of the shell 10.

In Fig.- 2, the cartridge, with a slightly modified 'form of shell 10, is inserted into the yalve chest 8. The hole 11 in the shell 10, is inthis instance, in communication with the motive fluid inlet passage 12 of the valve chest.

in Fig 3 th shell 10. is disposed of and the cartridge 18 inserted into a chamber 13 in opencommunication with the interior of r the valve chest through a port ld.

In operation, the cartridge is soaked in oil until it has become thoroughly impre nated therewith. The cartridge is then inserted into position to bring it in communication with the pressure fluid for operating the engine. This may be done in the manner shown in Figs. 1 and 2, by inserting the cartridge into a shell and inserting the shell into the pressure fluid supply passage or it 1nay be accomplished by inserting the cartridge itself without its shell into a chamber 1n communication with the fluid'pressure supply passage, as in Fig.3.

When the engine is running, there are fluctuations in pressure, or, in other words, pulsations in the pressure fluid supply passage due to the slightly reduced fluid pres-' sure when the engine takes the full charge of the motive fluid at the beginning of its sure supply passage will extract oil little by little from the cartridge thus obtaining a continuous supply of oil in the desired quantities'for the engine while the engine is running.

In actual of the engine ma bev insured by the fact that it can be rea ily determined how long one oil impregnated cartridgefwill last in the engine. For instance, if the operator of the engine is given three of these oil im? pregnated cartridges for operating the en gine a predetermined time and he should not return all three of these cartridges in their dry condition after the engine has been run the predetermined time, then the engine, has not been properly supplied with its-11b bricating oil, as there is onl one way that, these oil impregnated cartri ges can be run dry and that is by actually inserting them into the fluid pressure supply passage where they can be subjected to the pulsations due to the operation of the engine. A further very beneficial result by the use of these oil impregnated cartridges is that a 'surplus of oil cannot possibly be supplied to the engine. This will insure an enormous saving in oil and thereby expensein the operation of the engine. This economical method of supplying oil to the en ine will also permit the machine to be use successfully in connection with rock drills for operating on free milling gold properties where the waste of oil on the rock will materially reduce the amalgamation, as the quantity of oil used with my improved oiler is so small that it will not be su'ficient to affect the mercury on the plates in this work. It is desirable that means be employed for transporting these cartridges. 1 therefore employ suitable boxes 15, each ar-' ranged to contain a cartridge.

"The parts shown and described but not claimed herein, form the subject matter of a co-pending application filed by me the sixteenth day of May, 1910, serial No.

561,715, of which this case is a division.

What I claim is 1. An oil distributing cartridge comprisa strip of oil absorbing material and a practice, the proper lubrication strip-of wire gauze rolled together to form .;i..gQIO1IS mass. An 'olldistributmg cartridge comprlsing a plug,- a pin'projecting therefrom, a

strip of oil absorbing material and a strip of wire gauze rolled together around said pin to form a porousmass. p

. 3.'An oil distributing cartridge comprising -atplu g, a pin projecting therefrom, a strip-of oil absorbing material and a strip of wire; gauze rolled together around said pin to form a porous massand means for securing s'aid porous mass in position on the pin.

1. An oil distributing cartridge comprising a screw threaded plug, a pin projectingi therefrom, a strip of oil absorbing materi and a strip of Wire gauze rolled together around said pin to form a orous mass and means engaging the pin of securing the porous mass in position thereon.

5. An oil distributing cartridge for a; fluid pressure supply passage comprising a hollow shell arranged to project into said Supply passage, a plug removably secured to the shell and an exposed porous body portion secured to the plug and projectin into said hollow shell, the hollow shell ing provided with one or more openings for bringing the said porous body portion into open communication with thefluid pressure supply passage.
